Re: HOW TO: Install and configure lm-sensors

This program will help you determine which I2C/SMBus modules you need to
load to use lm_sensors most effectively. You need to have i2c and
lm_sensors installed before running this program.
Also, you need to be `root', or at least have access to the /dev/i2c-*
files, for most things.
If you have patched your kernel and have some drivers built in, you can
safely answer NO if asked to load some modules. In this case, things may
seem a bit confusing, but they will still work.

It is generally safe and recommended to accept the default answers to all
questions, unless you know what you're doing.

We can start with probing for (PCI) I2C or SMBus adapters.
You do not need any special privileges for this.
Do you want to probe now? (YES/no): Yes
Probing for PCI bus adapters...
Use driver `i2c-sis96x' for device 00:02.1: Silicon Integrated Systems SMBus Controller
Probe succesfully concluded.

As you are not root, we can't load adapter modules. We will only scan
already loaded adapters.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.

To continue, we need module `i2c-dev' to be loaded.
If it is built-in into your kernel, you can safely skip this.
i2c-dev is already loaded.

We are now going to do the adapter probings. Some adapters may hang halfway
through; we can't really help that. Also, some chips will be double detected;
we choose the one with the highest confidence value in that case.
If you found that the adapter hung after probing a certain address, you can
specify that address to remain unprobed. That often
includes address 0x69 (clock chip).

Next adapter: SiS96x SMBus adapter at 0x8100
Do you want to scan it? (YES/no/selectively): YES
Can't open /dev/i2c-0

Some chips are also accessible through the ISA bus. ISA probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

As you are not root, we shall skip this step.

Some Super I/O chips may also contain sensors. Super I/O probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

Re: HOW TO: Install and configure lm-sensors

Hi!
Thanks for this HOWTO.... but I am struggling with one of the last steps. Everything goes fine until I try and modprobe the i2c sensor when I receive this message
FATAL : Module i2c_sensor not found.
Two things are strange : one is that I enter it as i2c-sensor (but it replies as i2c_sensor with an underscore).... and the second is that earlier on in the process I received confirmation that the i2c sensor was installed correctly :

To continue, we need module 'i2c-dev' to eb loaded. If it is built-in into your kernel, you can safely skip this. i2c-dev is not loaded. Do you want to load it now? (YES/NO) : YES Module loaded succesfully.

Re: HOW TO: Install and configure lm-sensors

Thanks for an excellent how-to. I've got this running although I'm not sure about two things. The two things I'm not sure about are 1.) the Vcore settings and why it's in alarm and 2.) my cpu temp reports 35 celsius but when I do a quick restart and check the hw monitor in BIOS it reports between 45 and 47 celsius while the motherboard temp and remote temp are within 1 degree celsius or match the temp reported by sensors.

# Set Fan limits
set fan1_min 1400
set fan4_min 1800
# Set Temp Limits
set temp1_min 10
set temp1_max 55
set temp2_min 10
set temp2_max 35
set temp3_min 10
set temp3_max 35

How can I adjust the temperature monitoring for the CPU to be more accurate and should I bother with adjusting the Vcore limits?
Any advice would be appreciated. I've also attached a full copy of my sensors.conf file to this post.

Re: HOW TO: Install and configure lm-sensors

As stated on the lm-sensors.org, you don't need the i2c package, since it's allready in the kernel.

Just download the lm-sensors package, READ THE DOCUMENTATION (there are some issues one needs to understand, it's well explained), run the mkdev.sh (from the prog directory in the lm-sensors package), and go with the sensors-detect. Should work fine now.
